Micromax A110-Battery under temperature

This is Kalpesh Dodiya, from Rajasthan. I believe in Micromax for delivering best mobile solution in cost effective way. I and my family have 3 cell phone which are only Micromax make.

From yesterday, first time, I am getting the message “Battery under temperature, please unplug supply” frequently while charging the phone. My phone was working well till yesterday, and now suddenly this error comes.
